When performing field stripping of the M500A1 service shotgun, which component is removed first?

When performing field stripping of the M500A1 service shotgun, the correct first component to remove is the barrel. This process is critical for maintenance and cleaning, ensuring that the firearm operates safely and efficiently.

Removing the barrel first allows for easier access to the internal components of the shotgun. It is particularly important as it is the component that connects directly to the action of the shotgun and must be detached before other elements can be safely removed without damaging them or risking injury.

The other components, such as the receiver group, fore-end, and stock, rely on the removal of the barrel for their disassembly. Removing the barrel first simplifies the process and follows standard protocols for shotgun maintenance, ensuring that the service shotgun can be properly cleaned and serviced.
